We couldn't let our first-ever Melt Month go by without making a good-ol' tuna melt! So as our grand finale, we create the king of all tuna melts--with the help of your recommendations! Inside this melt: tuna (with celery, capers, and onions), havarti cheese, and cheddar cheese on lightly buttered and grilled sourdough. It's the perfect way to close out a very successful Melt Month!
